19 <br /> Existing Conditions (cont.) <br /> • Eight superblocks identified — no corresponding subdivision regulation <br /> requiring collector or major local roads to interconnect major corridors adjacent to <br /> superblocks. <br /> • Maps adopted in comprehensive plan include many proposed roads that are no <br /> longer planned. <br /> • Traffic Impact Study required for development expected to generate 800 trips per <br /> day. <br /> • Subdivision regulations state intent to limit access to major County roads but <br /> ,contain specific language to limit access only to collectors and arterials. <br /> Proposed: <br /> • Classification criteria: Interstate/Major Transportation Corridor, . Arterial, <br /> Collector, Major Local, Minor Local <br /> • All public roads outside municipalities'jurisdictional boundaries are classified. <br /> • Nine superblocks identified with corresponding subdivision regulation requiring <br /> collector or major local roads that connect major corridors adjacent to <br /> superblocks. <br /> • Maps reflect currently planned roads, but only existing roads are classified. <br /> • Traffic Impact Study required for development expected to generate 800 trips per <br /> day on an arterial or,350 trips per day on a collector or major local road. <br /> • Subdivision regulations that limit access from individual lots in new subdivisions <br /> to internal streets (minor local roads) and to require non-vehicular access <br /> easement to prohibit driveway or vehicular access along other roads adjacent to <br /> the subdivision. <br /> Implications <br /> Pros: <br /> • Consistent classification of roads throughout Orange County's jurisdiction. <br /> • Promote consistency with classifications of roads in other jurisdictions. <br /> • Limit access onto major roads. (NVA) <br /> • Identify spatial "superblocks" to interconnect major corridors and provide for <br /> those connectors through subdivision process. <br /> • Assure adequate road right-of-way. <br /> • Provide for Traffic Impact Study based on development size and road class. <br /> • Assure maintenance of rural character (buffers based on functional.classification). <br /> • Provide framework for other transportation plans/programs: Thoroughfare Plan, <br /> Transportation Improvement Program (TIP), MPO 2025 Long Range Transportation <br /> Plan. <br /> Cons: • Possible increased costs for developments of 35 to 79 lots; <br /> • May require more roads in subdivisions of medium size (by limiting <br /> driveway access to major local roads within the subdivision). <br /> \\CARR\SYS\PLANNING\KLI NCOLN\compplan\abstract.doc\2-18-00 <br />
